To all whom it may concern:

Be it known that I, JOSEPH P. HALLEN- BECK, a citizen of the UnitedStates, residing in the city of New York, in the State of New York, haveinvented certain new and useful Improvements in Button-Sewing Machines,of which the following is a specification, reference being had to theaccompanying drawings, in which similar parts are marked by like lettersin the differentviews, and the directions in which some of the partsmove are indicated by adj aeent arrows.

This invention relates to machines for sewing to clothing and otherarticles or fabrics buttons having perforations or eyes through themfrom side to side; but some parts of the invention are applicable tomachines for sewing on buttons having shank-eyes.

The general objects of this invention are to furnish a sewing-machinewith excellent mechanism for holding and intermittingly moving a buttonhaving four eyes and presenting the eyes in succession to the needle tosew on. the button by stitches from eye to eye progressively around thecircuit of the eyes, to provide such mechanism with adj usting deviceswhereby buttons having eyes at widely different distances apart can bethus sewed on, to provide such mechanism with adj usting devices wherebybuttons having four eyes or two eyes can be sewed on by stitchesextending to and fro between two opposite eyes and across the center ofthe button, to produce a button holder and carrier having superior meansfor receiving and holding such buttons and applying them to the fabricin the sewing-machine, to furnish the button holder and carrier withadjustable devices for holding and carrying buttons of very differentsizes, to provide the button-carrying mechanism with excellent means forantomatically securing the sewing on of a button by a certainpredetermined number of stitches, to provide such means with adjustingdevices whereby the sewing on of buttons by certain different numbers ofstitches can be secured, to provide means for automatically stopping thesewing-machine when the button-carrier shall have moved a certainpredetermined number of steps, and to provide a device whereby themachine'can be conveniently started and kept in motion. Other objects ofthe invention are hereinafter set forth. These objects are attained bythe mechanism illustrated in the accompanying drawings, in which Figure1 represents in side elevation. and partly in section a button-sewingmachine embodying one form of this invention, the section being mainlyat about the line .2 z in Fig. 2, which is a plan of the under side ofthe same machine. Fig. 3 shows a section of a portion of the bed-plateofthe same machine at the said line .2 z and an elevation of some partsof the mechanism, as seen in the direction of the arrow '1 in Fig. 2.Fig. i represents a section of the lower portion of the same machine atthe line or a," in Fi 2 and an elevation of some parts as viewed in thedirection pointed by the arrow 10, and Fig. 4 is a plan' and partialsection of parts at the line 20 10 in Fig. l.

Figs. 6, 7, and 8 represent some detached parts of the mechanismshown in 2. Fig. 9 shows in plan and on a larger scale the button holding and carrying mechanism represented in elevation in Fig. 1, and Fig.10 shows the same mechanism in partial section at the line i t in Fig.9. Fig. 11 is a plan of the under side of a part of the button-holdershown in Figs. 9 and 10; and Figs. 12, 12, and 13 are isometricalrepresentations of some detached parts of the same button-holder. Figs.let. 15, 16, 17, 18, 19, 20, 21, and 22 are isometrical illustrations ofdetached parts of the same button holding and carrying mechanism shownin Figs. 9 and 10. I

This invention is mainly applicable to various kinds of well-knownsewing-machines. The drawings illustrate it applied to a sewingmachinemanufactured by the Singer Manufacturing Company. Of that machine, Arepresents the bed-plate; A, the overhanging arm; B, the reyolubledriving-shaft; B, the needle-bar, which is depressed and elevated ateach revolution of said drivingshaft; C, the shaft which carries thehooked shuttle and is oscillated at each revolution of the driving-shaftby the intervening crank B connecting-rod B rock-shaft 0, having thearms 0 C and the arm (3 on the shaft 0 and engaging the arm 0 and O isthe feed-actuatin g rock-shaft having an arm 0, connected with thedriving-shaft by the rod 13 and eccentric B As a means for carrying abutton-holder holding a button, as Y, Figs. 9 and 10, having four eyes 12 3 4, in a circuit, so as to present each of the eyes in succession tothe needle to of the sewing-machine, the button-holder is secured to aprimary slide D, having a socket b, Fig. 16, with a crank-pin oreccentric E, fitting in said socket and secured to a revoluble shaft orcarrier F, mounted to rotate in a fixed position or socket b, Fig. 10,,and connected to the. driving mechanism of the sewing-machine by deviceswhich cause the rotation of said crank-pin or eccentric by steps ofequal length and equal in number to the number of eyes in the button.The slide D is also provided or furnished with a secondary slide G,having a guideway, as c c, for said primary slide and furnished withmeans for insuring the movement of said secondary slide bodily andequally in all its parts to and fro laterally to said primary slide andsaid guideway, so that the intermittent rotation of said cranlcpin oreccentric E causes the positive crank-pin or eccentric.

step-by-step movement of every part of said primary slide and attachedbutton-holder in a true circle equal in diameter to the diameter of thecircle described by the center of said In carrying out this part of myinvention any suitable known means may be used to secure the movement ofsaid secondary slide bodily to and fro laterally to said primary slidein a course perpendicular or somewhat inclined to said primary slide orin an arc of a circle or a curved course.

As a superior means for accurately guiding the secondary slide G and theprimary slide D, with its'attached button-holder, when actuated bytheeccentric E, fitting in the socket b in theprimary slide, I provide astationary base-plate H, Figs. 9, 10, and 14, which supports the twoslides and has a guideway (2 cl, Fig. 14, in which fit and slide wingsc, Fig. 15, on the slide G, which has guides c c, in which the primaryslide D fits and is moved to and fro by the eccentric E, having itscarrier F mounted to rotate in and 011 said baseplate.

To provide means for properly presenting to the needle of thesewing-machine buttons having their eyes in circles of differentdiameters or at various distances apart, I combine with the primaryslide and its attached button-holder a laterally-movable guideway forthe primary slide, means to direct the lateral movements of saidguideway, an eccentric fitting in a socket in the primary slide, arevoluble support which carries the eccentric and revolves it step bystep, and means by which the eccentric can be secured to its saidsupport at different distances from its axis of revolution.

To provide means for securing the eccentric upon its carrier atdifferent distances from its axis of revolution, I form the eccentricE,Figs. 10, 18, and 19, and its carrier F, Figs. 10, 14, and 17, one witha radial groove f and the other with a corresponding tongue f, adaptedto fit and slide in said groove, and have through the eccentric asuitable perforation f and a clampingbolt I, extending through theperforation f and engaging with the carrier F, whereby the eccentric canbe secured to the carrier at Whatever position it shall be set thereon.

To facilitate the adjustment of the eccentric E on its carrier F, thereis introduced upon the eccentric a cap-piece I, Figs. 9, 10, and 20,having a central perforation g, through which the clamping-bolt Iextends, and a camslot h, into which extends a pin 1', Figs. 10 and- 19,fast on the eccentric, so that upon loosening the clamping-bolt andturning the cappiece I to or fro uponthe eccentric and about the bolt Ias a pivot the eccentric will he slid radially along the ways ff by thecam-slot h and pin 11 in or out upon the carrier F to differentdistances from its axis of rotation, and can be there clamped fast withthe cap-piece I by tightening said clamping-bolt.

To further facilitate the adjustment of the eccentric upon its carrier,I form in the periphery of the carrier F a recess j, Figs. 14 and 17,and also form in the stationary support II of the carrier a slot j, soarranged that when the carrier is turned into a certain position itsrecess j will register with or be as an extension of the slot j, asshown in Fig. 14. I also have a stop-bolt J, Fig. 22, which can then beinserted through the slot j into the recess j, so as to prevent theturning of the carrier F while the eccentric E is being readjusted andclamped fast thereon, as above described, and so that the bolt J can bewithdrawn from the recess j to let the carrier revolve.

As regards the above-described parts of my invention, the button-holderattached to the slide D may be of any suitable known kind.

To provide a button-sewing machine with, improved means for convenientlyreceiving,

centering, and securely holding and carrying buttons having eyes throughthem, I have a fabric-presser K, Figs. 9 and 10, so secured to asuitable carrier, as D, that said fabricpresser can be freely elevatedand depressed and retained upon the fabric, and have the foot of saidpresser formed with a recess e and provided at the sides and end of thatrecess with lateral guide-bearings is, Fig. 9, so as to just permit abutton to be insertededgewise between them and thereby centered, saidlateral bearings being furnished with thin lips Z, projecting inward atthe lower edges of the bearings. Ialso have a somewhat elasticbutton-presser L, attached at one end to the ICC IIO

shank of the fabric-presser K and having its foot formed with a recess cand shaped and arranged so as to permit the button to be easily pressedin between it and the lips Z and the edge-bearings 7r, and so as to thenpress down upon the inserted button outside of the circuit of its eyes,and thereby securely hold the button when such button-holder is elevatedto permit the insertion and removal of buttons and when depressed uponthe fabric X, as in Fig. 10, while sewing on a button.

Any suitable known means can be used to secure the button-holder to itscarrier and to elevate and depress the sameas, for instance, such as isshown in Figs. 1, 9, and 10, wherein a part K, to which the part K isfirmly attached, is hinged at cl to a standard (Z on a part D, which isfirmly attached to the carrier D, and has a vertically-adjustable screwpost (1 extending upward loosely through an aperture in the part K andsurrounded by a spring d", compressed between the parts D and K, and acam-lever d is mounted on the post (i over the part K, which is pressedupward against the cam-lever by the spring (1*. When the cam-lever d isturned into its position in Figs. 9 and 10, it presses the button-holderdown upon the fabric X, and thereby clamps the fabric upon the thinplate D which is attached to the part D and extends over and slides uponthe cloth-plate a, Fig. 10, and has an aperture d, Fig. 21, about theneedle-hole a and of greater size than the circle of the eyes of thebuttons to be sewed on. "When the camlever d is turned into anotherposition, the spring CP'GlGVELtGS the button-holder in the course of thebroken line 6 in Fig. to permit the free removal from the button-holderof a button sewed to a fabric and the easy insertion of another buttoninto the buttonholder.

for example, by having the seat portion Z of the part L rest on the endsof four screws 0, which fit in and are adjustable through screwsockets 0Fig. 12, through the part Kand a clamp-screw c havingits head bearing onthe part L and its shank extending through a perforation a, Fig. 13, inthat part, and screwing into a screw-socket c in the part K.

hen the button-holder is to be used to hold buttons ofequal-diameters,thebearings for the edge of the button and the lips Zfor supporting the under side of its rim may all be on one integralstock.

To make the button-holder capable of receiving and holding buttons ofvery different diameters, I provide three sub-feet m, Fig. 12, each witha lateral bearing 70 and lip Z, and with a tongue 71, having therein ascrewsocket n and extending upward and fitting into one of three longerslots of, Fig. 12, arranged as at three sides of a square through theplate of the fabric-presser K, and each furnished with a clamp-screw nfitting in the screw-sooket a, and the under side of the head of thescrew bearing upon said slotted plate, substantially as indicated byFigs. 9 and 10, so that thereby the three sub-feet m can be readilyadjusted and firmly secured to said plate with their guide-bearings 7cat various distances from a commoncenter. The lips Z may be rigid on thesub-feet m, or may consist of the free projecting ends of thin sheetsprings extending under and along the sub-feet and united to the heelsthereof, as indicated by the lines at m in Figs. 10 and 12?. By theabove-described adj ustability of the button-holder it is adapted toreceive and hold buttons of equal diameters and diderent thicknesses,and buttons of equal thicknesses and different diameters, and buttons ofdifferent diameters and different thicknesses.

As regards the above-described parts of my invention, any suitable-knownmeans can be used to revolve the carrier F of the eccentric E step bystep in concord with the movements of the needle-carrier of thesewing-machine.

As an improved means for that purpose, I

have fast on the carrier F a bevel-gear F, Figs. 10, 1, and 2, engagingwith a bevel-gear M, mounted to freely rotate upon the oscillating shaft0, supported by fixed bearings y, and I have fast on the gear M aratchet M, Figs. 2, 4, and 8, furnished with a driving-pawl N andpawl-carrier N, mounted to too vibrate on shaft 0, and. having an arm Njointed to a rod N which is jointed to an arm 0 fast on the rock-shaftO, which is mounted on the bearings 03 and has an arm 0, con nected tothe driving-shaft B by the eccentric B and connecting-rod 13, wherebythe carrier F and eccentric E will be turned a step at each revolutionof said driving-shaft.

To render the mechanism capable of sewing on buttons having four eyes bystitches from eye to eye in succession around the circuit of the eyes,and also capable of sewing on buttons by stitches extending across thecenter of the button between two opposite eyes, the gear M may haveteeth of a number multiple of the number of teeth in the gear F, and thenumber of teeth in the ratchet M maybe equal to or a multiple of theproduct of the number four and the ratio of the numbers of teeth in thetwo gears as, for example, when the number of teeth in the gear M iseighteen and in the gear F is nine the ratio is two, which multiplied byfour gives the product eight as a proper number of teeth for saidratchet; also, the rod N may be jointed to the point 0 to the point 0.WVith this construction when the rod N is jointed at 0 to the arm 0 asshown by full lines in Fig. 4, the pawl N will be moved by the arm so asto turn the ratchet M. a step equal to only one of its eight teeth, andthereby turn the gear F, shaft F, and eccentric E through only onefourthof a revolution, as required in sewing on four-eyed buttons from eye toeye in a circuit. When the rod N is jointed by the pivot-coupling P, orits equivalent, to the arm 0? at 0, Fig. 4, the pawl N will be moved byeach rocking movement of said arm so far as to turn the ratchet M a stepequal to two of its eight teeth, and thereby turn the gear M throughone-fourth of a revolution and the gear F, carrier F, and eccentric Eone-half of a revolution, as when stitching across the center of abutton through and between its opposite eyes.

M is a collar fastened adj ustably to the shaft 0 to retain the gear Min proper engagement with the gear F and to keep the driving pawl N andits carrier N in proper relation to the ratchet M, and M is anadjustable friction-brake bearing against the sleeve of said ratchet tosecure its accurate movement by said driving-pawl and to prevent themovement of the ratchet by the shaft which supports'it.

Q is a friction-disk fast on the driving-shaft B, and Q is acorresponding friction-disk, grooved to receive a driving belt orb'and'and loose upon and slightly movable along that shaft. R is ashipper mounted on a'stationary pivot at p and arranged so that uponmoving it in the direction of the arrows to in Fig; 1 the disk Q whilerevolving will be pressed by the shipper against the disk Q to rotateit, 4

and thereby the shaft B, and so that upon moving the shipper in theopposite direction it will release the disk Q from the disk Q to let itand the shaft 13 stop.

R is a brake united to the shipper R and arranged so that when theshipper releases the disk Q from the disk Q the brake will then bearagainst a projecting part 19 of the disk Q, as shown in Fig. 1, to stopthe machine, and so that when the shipper presses the disk Q against thedisk Q the brake R will be removed a little from the projecting part 19of the latter disk, as in Fig. 2.

S is a rod jointed at 132 to the shipperR and mounted to slide to andfro lengthwise in bearings through stationary brackets or lugs 11. 10The rod S has a collar '8 fastened thereon, and is furnished with asprings which is compressed between the collar S and lug 10 so as toconstantly tend to move the rod S in the direction of the arrow Q2 andthereby move the shipper B, so as to release.

the disk Q from the disk Q and apply the brake R to the former disk.Another collar S is fast on the rod S and has lugs q, between which is apin g on the short arm of a lever T, which is pivoted at to a bracket gon the bed-plate A, so that by pressing down the long arm of that lever,from its position in Fig. 1 to its position in Fig. 3 the rod S will bemoved in the direction of the arrow 0 Fig. 1, in opposition to thepressure of the spring S and will move the shipper so as to press thedisk Q againstthe disk Q and remove the brake R from the latter disk,and thereby start the machine and keep it in motion.

To avoid all necessity for continuously.

pressing down the long arm of the lever T while the machine is inoperation, and to provide means for automatically stopping the machinewhen it has made a certain predetermined number of stitches in sewing ona button, I provide a revoluble thrust-bearing U, Figs. 1, 2, 3, 6, and7, for the slide-rod S and the follower U on said rod, and have on saidrevoluble bearing a ratchet U Fig. 5, furnished with a driving-pawl Vand its carrier V, pivoted at r to'a connecting-rod W, which is jointedto an arm 0 on the rockshaft 0, from which the button-feeding1nechanismis actuated, so that for each step movement of the button-carrier thethrust-bearing U will be turned .a step. I also have the parts U Uformed with abrupt ledges s s and with contiguous bearing surfaces 3 3whereby during a large portion of each revolution of the thrust-bearingU the slide-rod S is held, in opposition to the pressure of the springSin the position to keep the loose driving-disk step rotation of thebearing U its ledge 8 passes the corresponding part 8 of the follower Uthe rod S and shipper R will be instantly moved by the spring S so as torelease the disk Q from the disk Q and apply the brake R to the latterdisk, and thereby stop the machine. When the machine thus automaticallystops in using it, the sewing on of a button is usually completed, andthe sewed-on button should be removed from the button-holder and anotherbutton inserted in the holder, and therebydepressed and held in properplace on the fabric. By then pulling down the long armof the lever T;which may be connected with a foot-lever for that purpose, the slide-rodS will be moved so as to start the machine, as above described, and uponthen holding down that lever until the button-carrier shall have moved afew steps the thrust-bearing U will have turned so as to bring itssurface s opposite to the surface 3 of the follower, at which time thelever T should be released to let the follower bear against thethrust-bearing until in its rotation its ledge 3 just passes the ledge sof the follower and the machine then stops.

The ratchet U Fig. 5, has a suflicient number of teeth to permit themechanism to sew on a four-eyed button by stitches from eye to eye in acircuit repeatedly while the ratchet and the thrust-bearing U revolve0nce.'

To make the mechanism capable of moving the button-holder differentnumbers of steps during a rotation of said thrust-bearng, as isgenerally desirable and important in using the mechanism to sew onbuttons through ditferent numbers of eyes, I joint the pawl-operatingrod \V to the arm 0 of the rock-shaft O by a pivot-coupling'X, Figs. 5and 5=,'which is adjustable along that arm to different distances fromthe rock-shaft, whereby the pawl V canbe caused to revolve the ratchet Uand thrust-bearing U by steps each equal in angular extent or degree tothat of either one, two, ormore teeth of the ratchet at each to-and-fromovement of said rockshaft.

S is a collar adj ustably secured to the rod S to variously limit themovements of that red in the direction of the arrow The pawl-carrier Vis mounted loosely on the rod S, and between that pawl-carrier and thebracket a is a loose sleeve V on said rod. The thrust-bearing U andratchet U are united by a sleeve U which is loose on the rod S and isfurnished with an adjustable friction-bearing V to insure more accuratestepby-step movements of the ratchet by its driving-pawl.
